Venture Capital

Threshold Ventures

Threshold Ventures is an early-stage venture capital firm based in Menlo Park, California that backs founder-led technology companies at the threshold of breakout growth. Threshold is the 2019 rebrand of Draper Fisher Jurvetson (DFJ), the storied Sand Hill Road firm founded in 1985; managing partners Emily Melton and Josh Stein spun the venture practice into an independent, focused fund. Threshold pursues a high-conviction strategy, concentrating on a small number of Series A and Series B investments and partnering hands-on with founders for the long term, frequently holding board seats through IPO and beyond. The firm invests across enterprise software and SaaS, developer tools and infrastructure, fintech, digital health and healthcare, and AI. Its portfolio has produced 10 unicorns, 3 IPOs, and 17 acquisitions, and includes Box, Twilio, Redfin, Remitly, Doximity, Rippling, LaunchDarkly, Livongo, and Talkdesk. Threshold has invested in roughly 87 companies and raised a ~$250M fund following the rebrand.

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
